This is the daily demand profile for electricity.
Forgive me - it’s not about electrical supply demand - it’s about the capacity to provide enough for the increased demand in terms of new connectivity and the associated loads this puts on the networks -my fault if I wasn’t clear

Whilst travel assist isn't just an EV thing, the implementation and smoothness of control is much better, the electric drivetrain adds a layer of smooth control that mean I use it a lot. We had a golf with travel assist a few months ago and it was not the same, quite odd at slow speeds with the auto box/engine adding this notchy control at times that made me switch it off.Travel assist isn't just an EV thing.
Is "EV travel sickness" a thing? My son was prone to getting car sick when younger, 10 ish, seems to have faded now he is 14.
I only brought up the travel sickness because I felt it was the cars weight and damping that contributed to it. the DCC has a very large range (larger than the adaptive suspension on the BMW X3), and so I generally have it in individual on the softest setting which really makes for a smooth ride normally, but is clearly underdamped for badly undulating roads with the amount of weight it carries so has too much overshoot leading to this bouncier feeling, but on the hardest setting it tracks much better, with no overshoot and reduces the car sickness, but does make it a bit more fidgety.. However we are talking B roads in the lake district, I grew up there and getting car sick in the back of a Metro was a regular occurance!

Have a golf at the mo, travel assist is superb, use it all the time, expect it is smoother with an EV though.

Not knocking that your graphs are wrong but surprised usage is exactly the same in winter between 3.30am and 8am as the rest of the year. I know I dont bother putting any lights on atm when i get up at 5.30am and at work all out floodlights are on sensors and go off before 6am whereas in winter they can be on until 9am on dark days.
You were perfectly clear, the point that @chanjy was making is that the vast majority of EV charging can be done in that bit of the curve that’s lower (E.g. not between 6am and 8pm).
I totally get the usage pattern for a rapid charger closely matches the usual energy demand curve but in reality, they represent a small fraction of the energy used by the EV fleet.
The local and national grid is built to cater to peek demand, outside the times of peek demand there is plenty of generation and distribution capacity. For example, wind turbines are often turned off at night because there is too much electricity and not enough demand.
You can’t say the same for electric heat, that will add to peak demand but that isn’t the topic of this thread.
This. Same in my x5 45e. On normal mode the suspension is like a Rolls Royce on the roads but on undulating roads and weighing 2.7 tonnes, it bounces around far too much!!! I forgot last night to switch it over to sports suspension on my way home and wondered what the hell was happening!!!
Co Charger – the Platform That Lets You Share a Charge Point within Your Local Community
UK technology innovation for GenZ - whether it would be against Octopus T&C'sCo Charger is developing a community that helps to accelerate electric vehicle (EV) adoption. Through our app, we enable people who cannot charge a vehicle at home, to do so within quick walking distance of their home. We’re establishing and growing local communities of Co Charger Hosts, enabling people in their immediate locality to charge electric vehicles.
Doesn't plugshare already do this

Co charger has been going ages. I’m a host, had a local guy in an i3 charge twice… on my rates and hence low pricing I should be getting busier 
Quite different to plugshare/Zap-Map where home chargers simply pop up on the database to be honest, co charger also deals with the transaction of cash too.

National Grid’s view says otherwise.
Time of use energy tariffs will steer people to using EV charging when the demand peak is low. There is a lot of free capacity during the off-peak time from 9pm to 5am
Smart EV chargers will do this charging time adjustment automatically, taking signals for when to start & stop charging based on demand and therefore cost. Of course, the owner will be able to override this if required.

enough of the put-downs
he is right with respect to increasing national grid infrastructure, which they need to put in, to get the North sea wind farm power into the heart of the country,
in parents area of Norfolk/Suffolk residents currently complaining about new pylon routes, buried are too expensive.
e: hadn't looked up deatils before
The existing network in East Anglia currently carries around 3,200 megawatts (MW) of electricity generation. Over the next decade we expect more than 15,000 MW of new generation and 4,500 MW of new interconnection to connect in the region.

No doubt, we need more electric generation to meet the 2050 targets. Think the peak demand forecast is due to double to about 50GW, once heat pumps and EV's go mainstream. But there will always be a period of time where demand is low, mostly overnight where some of this demand can used during that time.
Indeed, gridserve have publicly stated that the usage profile of their rapid chargers essentially follows the grids usual demand curve.
When you think about it, that shouldn’t be a surprise, as it also follows general traffic patterns.
The forecast increase in peak demand is predominantly from space heating. Again if you think about it, your heating is generally only on when you are at home and awake. That means adding to those peak demand points.
My water and heating consume around 11,000 kWh a year. Even with a really good heat pump system, that’s still another 3200kwh of electric I’ll need and not a lot of it can happen outside of peak times (water heating only a small fraction of the cost) unless we deploy some other kind of thermal store.
The issue with the latter is where do you put it? All our heating equipment is upstairs and a thermal store big enough to run central heating will weigh hundreds of KGs.

Yup, and why Gridserve are also investing in Solar. Generation matches usage.
I guess the longer term answer is battery storage at home. Charge it up overnight and release it during the day.

It actually more likely to be V2H and V2G using BEV's sat around doing nothing during the day as well. I was reading about a scheme in the Netherlands (IIRC) where they have bi-directional charging on the car park for all the staff, over 30+ vehicles so far on it, they use intelligent demand to charge and discharge the cars, providing power for the offices directly, and when relevant the grid. They obviously have cut offs for low state of charge for the cars, and they are paid for the use of the electricity at a higher rate than they would be normally at peak times (like Agile does here) and have the option to buy back at a lower rate or take credits (kWh) to use when they want to.
Scale that idea up across entire countries where vehicles are static most of the day, and you have you storage, peak demand issue partially resolved.

So you paid 0.45p/kwh the most I pay is @ 0.28p Rapid with pod point when charging for 30mins = £8.40 but for me I use only half the charge or free charging when there is a free space if I can one!, Instavolt Rapid charges 0.57p/kwh so IONITY is expensive @ 0.69p the Zap map is good at finding chargers but most of them is off street parking @ 3.7/5/7kwh what a joke run by Ubitricity and others companies they say 50kwh I can't find them! Because they are very slow charging and depends how low you take the battery down = to the hours you need to stay there just like the free chargers all the Rapid spaces goes quickly so finding one is a waiting game in some areas like my town, I have a Peugeot E 2008 and it takes Type 2/CCS2 plug and some are the old ChAdeMO but you do find many Rapid chargers have both CCS2/ChAdeMO but in the EU the ChAdeMO is losing the fight with the CCS2.
I hope in future WIFI goes behind just your area! I hate using mobile Data to find charger points on the map but have too if your limited to DATA each month it's easy too racks up the bills as well if not checked, unless you have unlimited DATA then that's fine. but of cause anyone can use the unsafe hot spots if they choose, it's not safe for payment IMO. Many Rapid charger stations I found use contactless cards at the stations for payment no need to register! Saying that Zap Map app will show all the companies charging stations on the UK map @20336, but they don't tell you is many charge stations use only an app to work like pod point and others, it the same with off street it's a QR code charging and payment only system @7kwh lamppost it's ok if you live there and some off streets you only get two hours max, BP pulse is 0.45pkwh and have 9,000 charger points across the UK but ChargeMaster is the largest electric vehicle charging network in the UK.
This week I had to use Instavolt Rapid charger @0.57p/kwh 58mins 11sec cost me £14.41 didn't want to wait again for another day when to find pod point empty @ Tesco in my city there isn't a lot of charging stations vs EV owners The Local government didn't think this though enough. I read my council is going to install another 110 over the next 3 years what a big disappointment for a seaside town.

V2L/V2G
EV6 V2L capability/cars were delayed into usa - was it ? because the warranty impact of additional erratic loading on the cells needed evaluation,
it's not like the current demands on the battery from the drive motor, & generally, for full V2G that'll be an issue, if you are selling a 2nd hand car that has been dual purpose.
Lightening with its orientation towards commercial use must present that concern today (running arc welder, power tools ....) or later the Cybertruck
